Embodiment 1

[0028] Embodiment 1: as Figure 1-3 As shown, a trainer for simulating thoracoscopic surgery includes a fuselage 7, a monitor 1, a simulated endoscope 3, simulated surgical instruments and a control system, and the monitor 1 is fixed on the fuselage through a support arm 2 7 above, the simulated endoscope 3 and the simulated surgical instruments are all connected to the fuselage 7; the simulated endoscope 3 and the simulated surgical instruments are equipped with rotation sensors and displacement sensors, and the rotation sensors and displacement sensors are connected with the control system electrical connection; the control system includes a data receiving and processing device, a 3D model processing server and a 3D platform system server. Described simulation endoscope 3 comprises retractable mirror body 11, and the rotating knob 9 that adjusts angle is installed on the top of retractable mirror body 11, and electrical interface 12 is installed on the bottom of retractable ...

Embodiment 2

[0029] Embodiment 2: as Figure 1-4 As shown, compared with Embodiment 1, this embodiment also includes a force feedback device; a hardware control system, which is used to obtain the position information of the virtual surgical operation instrument, and generate the position signal based on the position information of the instrument. For the control signal to be provided to the force feedback device, the signal operated by the hardware is transmitted to the software through the USB signal protocol to perform the corresponding simulation algorithm, and finally displayed on the monitor in real time through the display system to realize various surgical operations of simulated thoracoscopic surgery .

[0030]The hardware control system can obtain the position information of the head of the simulated surgical instrument sliding relative to the fulcrum through a simulation algorithm; based on the position information of the head of the simulated surgical instrument, a control sign...

Embodiment 3

[0034] Embodiment 3: Simulating thoracoscopic left lower lobectomy, if the simulated left lower lobectomy is selected, a simulated left lung in the right decubitus view will be generated on the display screen. 1) Traction: Select the simulated thoracoscopic double-joint forceps from the right simulated surgical instrument 5, clamp the lung tissue at the basal segment of the left lower lung and pull it headward and lock it. This action simulates the pulling and exposing actions of the assistant during the operation. 2) Treat the lower pulmonary vein: select the simulated thoracoscopic suction device from the left simulated surgical instrument 4; select the simulated electric coagulation hook from the right simulated surgical instrument 5, and the suction device cooperates with the electric coagulation hook to free the inferior pulmonary ligament until the inferior pulmonary vein and the inferior pulmonary vein appear. Pulmonary ligament lymph nodes, replace the left simulated su...

Abstract

The invention disclose a simulation thoracoscopic surgery training aid, including a machine body, a surveillance device, a virtual endoscope, a virtual surgery machine and a control system, the surveillance device through a branch arm is fixed above the machine body, the virtual endoscope and the virtual surgery machine both connect with the machine body; the virtual endoscope and the virtual surgery machine are both provided with a rotating sensor and a displacement sensor, the rotating sensor and the displacement sensor are electrically connected with a control system; the control system includes a data receiving processing equipment, a 3D model processing server and a 3D platform system server. The training aid aims to provide a simulation thoracoscopic surgery training aid, enabling the surgeon through the training aid to conduct various thoracoscopic surgery simulation trainings.

Description

technical field [0001] The invention relates to the field of medical instruments, in particular to a trainer for simulating thoracoscopic surgery. Background technique [0002] With the continuous expansion and deepening of the application of virtual reality (Virtual Reality, VR) technology in the medical field, virtual surgery (Virtual Surgery) and VR surgical simulators have attracted more and more attention. Take the currently popular thoracoscopic minimally invasive surgery as an example. This kind of surgery makes a hole in the patient's chest, and inserts surgical instruments and cameras deep into the chest cavity. Reduce the wound, reduce the pain of the patient, and shorten the recovery time of the patient. This surgical method has brought good news to patients, but it puts forward higher requirements for doctors. Doctors must undergo sufficient training to master their eye-hand coordination and be competent for corresponding operations. Current training for this t...
